Great video. I uploaded a video to my channel a while back showing this. Using ice water will give you very good current output, but the ice will not last long.
Loads of negative comments on here. The guy made an interesting project that beginners might try…. To learn something… to make something. To all you smart alecs out there…. Channel your negative comments into doing something positive!!!
Peltier elements usually come with copper heat syncs so the tray with water is optional and simply popping it cold side facing away from a camp fire should do a good job.
I just defended my PhD thesis about thermoelectric generation and I have a suggestion for you. Inside most TE modules there is a layer of graphite that needs to be compressed in order for the modules to work properly. If you would clamp the modules together also during use, the power output from the generator would increase signififantly due to lower thermal (and to some extent also electrical) contact resistances inside the modules. The modules I've been working with should have a contact pressure of 1.2MPa. Such a clamping device would cause the whole generator to be a bit heavier but the increased performance would make it worth it. By the way, thanks for all great videos! :) // Olle
How did your design go? I saw a thermoelectric generator that fits over a gas powered lantern, using the heat energy to power old vacuum tube radios. Obviously this is from the 1940s (listen to the radio without AC power or a car battery). The idea is applicable today to charge our modern much more energy efficient devices, and can be extended to your cooking fire design requirement. One side hot, the other side cooler and it works with dissimilar metal wire instead of P-type N-type semiconductor junctions. The electricity was generated from hundreds (thousands?) of pairs of twisted together dissimilar metal wires. Twisted wire pairs instead of peltier plates can work at higher temperatures and without megapascals pressure without failing.
Hi I am abhilash and I am 13 years old and I like to do electronics and make projects. And u have made an awesome project and even I was thinking to make one earlier and I would now definitely make it. Keep up the good work. GREETINGS FROM INDIA .☺
Great project! Nice concept, and definitely seems like a simple way to convert the temperature difference into electricity. But those so called "peltier modules" are pretty inefficient, but as you said in the video, cheap and simple.
Your channel is the best DIY channel I've found because it's stuff that's genuinely useful. Colin Furze and Grant Thompson are entertaining, sure, but I can never imagine actually making their stuff the vast majority of the time.

It may be worth insulating your water bath to keep it cool except for the contact pads. Also trapping as much heat as possible on the underside without smothering the flame. Currently, the candles are basically heating up the exposed water bath.
There is quite a bit to do on the efficiency side of this design. Firstly, all the thernoelectric generators are in series. This might not be that optimum of a plan. The issue is that the central element probably generate more energy than the side once. The aluminium heat spreeder really don´t spreed the heat that far. A solution to that problem could be to wire them 2x5 or 5x2 or 3x3 (and skip one) and for the case of the 5x2 or 3x3 use a step-up regulator in steed of a step down The second part is efficiency of the candles. Most of the heat is wasted. It´s not turned into electricity, and not even into heat in the pan. One way of making this... sure have to rebuild quite a lot of the design, is to make a funnel. That is collect all the heat of the candles, funnel it up a "chimney" and have the thermal generators. Could have 4x2 and have a upper and lower stack in parallell. Or make a really narrow chimney and have 2 facing each other and have them stack 5 high. The last problem it self is the peltier elements... they are simply not that efficient. A normal rankine engine is about 4 times more efficent... but of cause.. find a home size rankine engine might not be that simple.
Just remember to install diodes between the parallel TECs to prevent one branch from back feeding into another if the voltage is not exactly matched, which it won't be. Also the diodes will decrease the efficiency a little
What if you used this technology to make a thermoelectric solar panel. You only would need to scale things up and use a aluminium manifold as heat sink
@@mequedo this would be useless as it would be expensive, inefficient and unnecessarily complex relative to solar panels, however it would be possible to create an RTG with this technology, hell this is how an RTG works. A better version of a thermal solar panel would be a heliostat which boils water into steam that drives a generator.
So awesome! We party on the beaches of Lake Powell (az/utah) and this will prevent people from firing up their gasoline generators to charge their phones keeping the lake quiet at night! Relatively inexpensive to make a few or 5 and a fun conversation piece that will help my friends!
Good video! The science behind peltiers is pretty cool/fascinating and the application is fairly easy to apply to just about any heat source. Unfortunately, the tricky part/catch22 is coming up with an ultra-efficient (no cost) way to heat the hot side, while also efficiently cooling/pulling heat away from the cold side. Attaching a bunch of peltiers to a free heat source, such as (ie) a "fire-ring" (while camping in the middle of Winter) would work really well... but very few people are going to want to sit around a campfire in the middle of Winter/single-digit temps to take advantage of the limited electricity being produced. On a side note, if a person had a free/unlimited supply of candles and ice, the device in the video would be great to have around... especially during a power outage.
Hello sir, I'm very thrilled after watching this video and I'm glad I found it. The Surprising part is I wanted to do my final year major project on Thermoelectrics and after finding this video, my spirits were boosted. Thank you for this wonderful project. It helped me, to learn more about it.

@@marvinmarvini8629i don't know how much power they'll generate, but they'll probably generate fuck all. assuming the heatsink is at an ambient 20°c, that'll leave you with only 30°c of temperature difference. you'll generate maybe 100mW. you want something like a TGPR-10W-4V-40S run at 200+°c of temperature difference
Awesome! What about putting everything in parallel 3 by 3? In this way, you'll have a lower voltage (max 3 or 4 volts) and a quite nice current. You can plug the new set up to a DC to DC step up boost converter and maybe obtain a better efficiency. Another nice ting could be putting a temp sensor like a pt100 and create a sort of an arduino overheating protection switch so you can fine tune the assembly in order to maximise the efficiency. A versus between a couple of arrangements could be quite interesting! Nice job and keep on doing interesting things like these!
Hi there! Quick question -- what is the reason to wait for the regulator to reach 10V before turning it on? Also, is the reason for using a larger bread tin like that one you've used in your video so that it can generate more voltage? Not being an electrical engineer myself, I can only assume that more bread tin = more time it takes to warm up the water = longer/more consistent charging time? In other words, if you used a smaller tin, would you not be able to generate enough voltage? Thanks for this awesome video!!
In colder areas, would the reverse work? Let’s say we flip this around so the ‘cold’ side is on the bottom, sitting on the ground (or a metal stand). Now, the top section is where we want the heat. We use either a rock or brick that’s been sufficiently warmed, and use that for the heat. Since bricks and rocks tend to hold heat for longer, it will not only generate more electricity, but the times necessary to reheat the brick will be much shorter than changing the water every ten minutes.
I'm really tempted to buy those thermoelectric things now, but I don't have a use for them. They will become one of those "I'll probably use them at some point" things lying around my house.
+LazerLord10 Yup, and then you find out that they draw 2 Amps at 12 Volts in cooling mode, and only produce one milli-amp of current in reverse mode, and they stay in the drawer were you put them when you got them.

This is pretty awesome for us fools that live in a place literally called "Hurricane Alley" and instead of Winter, Spring, Summer, and Fall... we have Hot, Sweaty, HURRICANE SEASON!, five days of nice weather, boiling hot again. We lose power pretty regularly once a year during hurricane season... so I might actually make one of these for my mom. I can make it look all nice and stuff. She has thousands of those tea candles, so she's set!
My masters dissertation was on a project that included these Peltier elements, interesting little devices. When you put current in them one side of the plate gets hot and the other cold, when you switch the polarities the hot and cold sides switch places, and the whole process is reversible - meaning when you add heat, current is produced.
I don't know if there's a video already out there but I'm really curious if liquid nitrogen or dry ice would just destroy them or if it will still work
This is an good idea for commercial kitchen, with ovens running all day. Water flow and up to 300 C resistant components will be needed. And the system attached to an 12V rechargeable battery or regulated capacitor. So both free 12 energy and hot water is recycled for free.
this is brilliant. i live in canada... and a group us us go out to a cabin with no electricity for the weekend from time to time. this would be perfect to keep small devices charged and ready for the trip home. just put this device on the wood stove and chuck in some snow. i can imagine charging laptops on it already
Hi Murray try one of these Wood Stove TEGs at your cabin. www.tegmart.com/thermoelectric-generator-products/devil-watt-teg-power-15-watt-wood-burning-stove-thermoelectric-generator/
The idea itself is quite nice and might be useful for situations like "out in the jungle without electricity and the dire need to recharge something like a radio". Might be useful for special forces operating in denied areas... but I'm not happy with the safety of the implementation. The step down converter could be killed by a splash of water and the wires can easily get into contact with flames. A little bit more time invested in the safety and you might have a ready-to-sell product that could be a real life-saver. Still a good idea and video.
those thermoelectric plates are really cool. you should build a self-powered cooler using some solar panels and those plates. something that you could just leave out in the sun and it would keep your food way colder than a standard cooler
I would love to see this at scale, say, over a fire pit. You know, an apocalypse version lol given we had as large a stockpile of thermoelectric plates as we do TP
Quite inefficient but a cool project ! If you want to have the liquid very cool , try ice water and lots of salt , the salt will melt the ice quickly and lower the temperature of the water even below freezing point, it will be far more efficient than simple ice or ice and water.
A rather dumb question: You did show footage using the generator in a campfire, which could be a rather volatile and uncontrolled source of heat.... What prevents cables and electronic parts from melting? (simply put, i do not know the temperatures which, the components can withstand) ALSO: I saw a heat sink, can the generator work like providing the power for the heat sink with a little excess?
The circuit board was on the "cold" side of the system, so it wouldn't have to deal with the full heat of the fire. When you run a current through the device, it makes one side cold, and the other side hot. If you want to keep it running efficiently, you have to get rid of the heat by pulling it away and throwing it somewhere else. That's what the heatsink is for.
+fatherdoctor Most people think that the mere presence of heat is enough to generate power. that's incorrect. you need to have a FLOW of heat THROUGH the Peltier element in order to generate power. Since heat always wants to flow towards cold spots, you have the cold water at the top.
Looking to build my own outdoor wood furnace to heat our home and barn. while I'm at it I might as well build a TEG on the fire box. Thanks for the idea.
"This Sweepstakes is open only to those who are legal residents of the fifty (50) states of the U.S."... yeah, no chance to win for me.. But the video was good! :)

You are using the cheaper TEC (thermo electric cooling) modules. For optimal efficiency you ought to get the more exspensive TEG (thermo electric generator) modules. But a very cool project, I like the use of the baking tin for easy cooling.
@Gomey World - Oh good... let's all start mistyping words and not giving a crap. That would be so awesome... NOT. Feel free to skew truth and self-evident things all you want, just don't go crying when it begins to have a negative impact on society. Don't believe me (look around) look to history and note the moments in time when truth and self-evidence were at all-time lows vs all-time highs.
@@__WJK__ I think someone needs to look up the difference between correlation and causation. Mistyping a word is not "skewing truth", claiming unspecified bad things without evidence and pointing to unspecified points in history on the other hand... You are forgiven for your temporary insanity, it will pass when you get older and get more perspective on life ;)
@@beaconofwierd1883 - Ass-ume much...(?)...I'm 50yrs old (lol) So, how is world history not enough evidence for you(?) The main point I was trying to convey in my reply is, why do so many people get so defensive (or lackadaisical) when someone tries to inquire/question or correct someone else's word choice or spelling error(?) Calling attention to a mistake is a good thing... (ie) Would we not want an observant friend or guest (who walked into our home) to "not" tell us that the un-lit burner on our stove was still on...(?)...I should certainly hope we would. Another, less extreme example... it's well known that before a book gets published, paid proof-readers actually double-check the book writer's word choices and/or mistakes. I very much doubt writers get offended when the publisher's proofreader calls 'em up to ask if they "actually" meant to use a particular word that looks out of place... (i.e., thermometric(?) or thermoelectric(?) If I were a writer... I certainly wouldn't want a proofreader working for a publisher that didn't have a passion for truth and instead said, "I think we all know what the writer meant" ... go ahead and print the book...lol...
@@__WJK__ You're 50 and still think like a 15 year-old? That's depressing. Context matters, if someone misspeaks in a conversation and everyone understands what the person meant it's just rude to point it out. We probably differ on what a comment on TH-cam qualifies as, but I would definitely put it a lot closer to "casual conversation" than "published book" and I bet many others do too, which might explain why you think people get "offended" when they are being corrected. Also, I did not say world history isn't evidence, I said unspecific reference to world history isn't. I also mentioned something about correlation and causation which you conveniently forgot, though I doubt there's even a correlation between misspellings and "Truth/self-evidence".
I love everything about the concept except for mounting electronics over a steaming pot. If not shorting it out, the humidity will corrode the metal. -Justin
I thing i would change is to solder them in parallel and usa step up boost converter. Or just plug it in directy in a 1-6.5v to 5v usb converter module
If you guys wanna put you your money where you mouth is go ahead and put your phone over a pot of boiling water... Attaching the voltage regulator to the stand would have been a better idea in my opinion -R
The concept is fairly easy to apply to just about any heat source... the tricky part is coming up with an efficient way to cool/wick the heat away from the heatsink side of the peltier. (ie) Attaching a bunch of peltiers to a camping pot or "fire-ring" in the middle of Winter would work pretty well... but not many people are going to want to sit around/enjoy a fire in the middle of Winter. ;) ;) ;)
Can I connect the positive and negative wires together? Just asking before I accidentally break my research project, I don't major in electronics so Idk. Thank you for taking the time to reply..

Very well explained and narrated. You could get a job as a narrator if you don't have one already. I have got to do this. This is absolutely brilliant. What about making a bigger one to charge a 12v battery? Would that be possible?
That's pretty cool. I wonder if you could use the sunlight as the heat source (put a black plate on one side to heat up in sunlight), and then have it cooled from the bottom...
hey remember me? i commented on one of you videos when you had alot less subs saying you looked like a Game of thrones character! Its good too see how much your channel has grown!
I'm not sure if anyone else mentioned this, but why not fill it with water and put it in the freezer for a solid block of ice. I know you said snow and ice just seems a solid block in the tray would be easy prep also.
Great video, as always I must say! Are these the same as "Peltier" elements? I've used these decades ago to cool down an experimental setup during my studies, but in this scenario the use looks like the absolute reverse 🙂
Have been meaning to combine something like this with a chilly-bin and a tealight clay pot heater. But with a temperature based polarity swap switch for keeping the chilly-bin cold and the heater hot. Then switch again to charge a battery. Have all the parts except for a chilly-bin.

Over the years I've bought some.
All.laying around the house. Many projects tried. None of them were usefull.
This is pretty awesome for us fools that live in a place literally called "Hurricane Alley" and instead of Winter, Spring, Summer, and Fall... we have Hot, Sweaty, HURRICANE SEASON!, five days of nice weather, boiling hot again.
We lose power pretty regularly once a year during hurricane season... so I might actually make one of these for my mom. I can make it look all nice and stuff. She has thousands of those tea candles, so she's set!
Fixing hot plate at 50 degrees and the heat sink, which thermoelectric module would produce more power: TEC1-12702, TEC1-12706 or TEC1-12710?
Awesome!
Cheers!
+DIY Perks do you wan to make a camera jib
Thats what channels like Linus Tech Tips are for.
Mist8k what of you get a cpu heat sink and use the power it generates to Power the heat sinks fan

My masters dissertation was on a project that included these Peltier elements, interesting little devices. When you put current in them one side of the plate gets hot and the other cold, when you switch the polarities the hot and cold sides switch places, and the whole process is reversible - meaning when you add heat, current is produced.
Next Radioisotope thermoelectric generator please ;)
Yeah! I love cancer and radiation illness!
+Florian Daßler don't we all?!!!
Florian Daßler You'll be fine as long as you don't try to eat or snort the plutonium. Alpha radiation can't penetrate your skin.
The problem will be GETTING the plutonium.
I too enjoy my cells multiplying rapidly with lethal effects
Saved the vid to my apocalypse survival playlist
I don't know if there's a video already out there but I'm really curious if liquid nitrogen or dry ice would just destroy them or if it will still work
Cold doesn't harm them, only if the heat is high enough to melt the solder/glue that holds the individual sections of the Peltier modules together.
This is an good idea for commercial kitchen, with ovens running all day. Water flow and up to 300 C resistant components will be needed. And the system attached to an 12V rechargeable battery or regulated capacitor. So both free 12 energy and hot water is recycled for free.
I love the amazing quality of your videos!
this is brilliant. i live in canada... and a group us us go out to a cabin with no electricity for the weekend from time to time. this would be perfect to keep small devices charged and ready for the trip home. just put this device on the wood stove and chuck in some snow. i can imagine charging laptops on it already
hum... i dont trust anyone who has an iphone...
Hi Murray try one of these Wood Stove TEGs at your cabin. www.tegmart.com/thermoelectric-generator-products/devil-watt-teg-power-15-watt-wood-burning-stove-thermoelectric-generator/
another great video man hope u make more videos frequently :D :D
samitha sheshan Then they wouldn't be as good
The idea itself is quite nice and might be useful for situations like "out in the jungle without electricity and the dire need to recharge something like a radio". Might be useful for special forces operating in denied areas... but I'm not happy with the safety of the implementation. The step down converter could be killed by a splash of water and the wires can easily get into contact with flames. A little bit more time invested in the safety and you might have a ready-to-sell product that could be a real life-saver. Still a good idea and video.
Wow Matt this is really clever! Nicely made too. Always love the format of your videos, very clear and informative :)
those thermoelectric plates are really cool. you should build a self-powered cooler using some solar panels and those plates. something that you could just leave out in the sun and it would keep your food way colder than a standard cooler
I would love to see this at scale, say, over a fire pit. You know, an apocalypse version lol given we had as large a stockpile of thermoelectric plates as we do TP
Quite inefficient but a cool project ! If you want to have the liquid very cool , try ice water and lots of salt , the salt will melt the ice quickly and lower the temperature of the water even below freezing point, it will be far more efficient than simple ice or ice and water.
A rather dumb question:
You did show footage using the generator in a campfire, which could be a rather volatile and uncontrolled source of heat....
What prevents cables and electronic parts from melting?
(simply put, i do not know the temperatures which, the components can withstand)
ALSO: I saw a heat sink, can the generator work like providing the power for the heat sink with a little excess?
The circuit board was on the "cold" side of the system, so it wouldn't have to deal with the full heat of the fire.
When you run a current through the device, it makes one side cold, and the other side hot. If you want to keep it running efficiently, you have to get rid of the heat by pulling it away and throwing it somewhere else. That's what the heatsink is for.
+fatherdoctor Most people think that the mere presence of heat is enough to generate power. that's incorrect. you need to have a FLOW of heat THROUGH the Peltier element in order to generate power. Since heat always wants to flow towards cold spots, you have the cold water at the top.
the better way to do this is mount a heatsink with a big surface area and small fan. it will work as long as candles are burning
Nice vid but curious as to why not a combo series/parallel arrangement if the voltage is too high?
Thank you for yet another interesting video! Very much appriciated the time and effort you put in them to make it look so professional! Big thumbs up!
Looking to build my own outdoor wood furnace to heat our home and barn. while I'm at it I might as well build a TEG on the fire box. Thanks for the idea.

"This Sweepstakes is open only to those who are legal residents of the fifty (50) states of the U.S."... yeah, no chance to win for me..
But the video was good! :)
And from 3 years in the past :(
piece of shit ameritard
I am short of words. But I can say thank you for the video. I am currently reading on that, but video clearly made me understand the concept. ❤🎉
Awesome idea!
Wow really inovative, what made you think of this, candels, water, regulator and all. My oh my creativity and science, at its best. SOOOOOO COOOOOL
7:04 - good look? ;)
+Arsyad Kamili Ahhhh...
Why don't we have these in our homes especially through out winter?
If built directly into our exterior walls for light , it would be nice.
Thanks for this video
**recieves a call** hey bro you won 10 tons of raw aluminum plates, tell us where you want us to deliver them
You are using the cheaper TEC (thermo electric cooling) modules. For optimal efficiency you ought to get the more exspensive TEG (thermo electric generator) modules.
But a very cool project, I like the use of the baking tin for easy cooling.
"Let's make a thermometric generator. Step one, buy a thermometric generator on eBay. Step 2... done..."
thermometric ????
@Gomey World - Oh good... let's all start mistyping words and not giving a crap. That would be so awesome... NOT. Feel free to skew truth and self-evident things all you want, just don't go crying when it begins to have a negative impact on society. Don't believe me (look around) look to history and note the moments in time when truth and self-evidence were at all-time lows vs all-time highs.
@@__WJK__ I think someone needs to look up the difference between correlation and causation.
Mistyping a word is not "skewing truth", claiming unspecified bad things without evidence and pointing to unspecified points in history on the other hand...
You are forgiven for your temporary insanity, it will pass when you get older and get more perspective on life ;)
@@beaconofwierd1883 - Ass-ume much...(?)...I'm 50yrs old (lol) So, how is world history not enough evidence for you(?) The main point I was trying to convey in my reply is, why do so many people get so defensive (or lackadaisical) when someone tries to inquire/question or correct someone else's word choice or spelling error(?) Calling attention to a mistake is a good thing... (ie) Would we not want an observant friend or guest (who walked into our home) to "not" tell us that the un-lit burner on our stove was still on...(?)...I should certainly hope we would. Another, less extreme example... it's well known that before a book gets published, paid proof-readers actually double-check the book writer's word choices and/or mistakes. I very much doubt writers get offended when the publisher's proofreader calls 'em up to ask if they "actually" meant to use a particular word that looks out of place... (i.e., thermometric(?) or thermoelectric(?) If I were a writer... I certainly wouldn't want a proofreader working for a publisher that didn't have a passion for truth and instead said, "I think we all know what the writer meant" ... go ahead and print the book...lol...
@@__WJK__ You're 50 and still think like a 15 year-old? That's depressing. Context matters, if someone misspeaks in a conversation and everyone understands what the person meant it's just rude to point it out. We probably differ on what a comment on TH-cam qualifies as, but I would definitely put it a lot closer to "casual conversation" than "published book" and I bet many others do too, which might explain why you think people get "offended" when they are being corrected.
Also, I did not say world history isn't evidence, I said unspecific reference to world history isn't. I also mentioned something about correlation and causation which you conveniently forgot, though I doubt there's even a correlation between misspellings and "Truth/self-evidence".
Your voice is so relaxing and makes this video more enjoyable.
I love everything about the concept except for mounting electronics over a steaming pot. If not shorting it out, the humidity will corrode the metal.
-Justin
it wont steam, the water wont go over 25°c
yeah I doubt its much of an issue. 10V 1A demineralised water meh...
I thing i would change is to solder them in parallel and usa step up boost converter. Or just plug it in directy in a 1-6.5v to 5v usb converter module
distilled water is non conductive, anyway, coat the electronics with plastidip or similar...
If you guys wanna put you your money where you mouth is go ahead and put your phone over a pot of boiling water... Attaching the voltage regulator to the stand would have been a better idea in my opinion -R
should've use a TEG to make it even better. instead of TEC
teg is way more expensive than tec, but totally agree!!!
123woefie this is true it even produces more electricity
you sir are a legend .. one day I will build one of your gadgets ..
I think I should let everyone know that, according to the terms and conditions of the giveaway, its only available to people who live in the USA
but hes in the UK
how the hell does that work
This is actually quite simple and really fun! I may actually do this project myself.
Imagine a camping pot made like this. Hang on. Someone's done this already right?
The concept is fairly easy to apply to just about any heat source... the tricky part is coming up with an efficient way to cool/wick the heat away from the heatsink side of the peltier. (ie) Attaching a bunch of peltiers to a camping pot or "fire-ring" in the middle of Winter would work pretty well... but not many people are going to want to sit around/enjoy a fire in the middle of Winter. ;) ;) ;)
Biolite Camp Stove
Can I connect the positive and negative wires together? Just asking before I accidentally break my research project, I don't major in electronics so Idk. Thank you for taking the time to reply..
Aaaaa, please somebody, someone reply. ;~;
No you cannot short the two
Short the two?? What do u mean?
It means you cannot connect positive and negative wires directly together becausenit will short
But in the video, he connected the red together with the black wires?
1:38 surprisingly inefficient as well
I live in Arizona, is there a way to reverse this set up using sun heat on top??
use a bonfire. Those candles cost more than a new battery.
I bought 100 candles for £1, so... nope. :)
+DIY Perks burn... 😏
+subin pariyar
wrecked ;d;
+Teemu M. reckted.
+DIY Perks Works in UK only i suppose :)
A while back I bought a BioLite stove which I believe works by the same principle. Feed it with wood and it can charge whatever can be charged with USB. And you can cook food on it.
Molten aluminum on one side and liquid nitrogen on the other? hmmm
Mains voltage
+SuperSilver301
Yeah about 120V but DC not AC.
But 120VDC could work for phone wall chargers, DC will just pass bridge rectifier.
What with him?
+Marco Bertoni the mains voltage goes through bridge rectifier to convert ac to dc, then the dc is lowered to 5v by step-down transformer :P
Bananovskyy Wait, a transformer only works with AC!
120VAC -> Step-down: 12VAC -> Full Bridge Rectifier™ -> 5V regulator
Voilà! 5V Direct current.
I have known about these for years... another cool project u can google is a candle powered radio.... hard to believe there aren't much comercial products like that
the best quality DIY video of the WEB!! Man, you're the best
Very well explained and narrated. You could get a job as a narrator if you don't have one already. I have got to do this. This is absolutely brilliant. What about making a bigger one to charge a 12v battery? Would that be possible?
Good stuff. I'm even thinking of using those thermoelectric plates to make a mini-fridge.
Combine an oil conversion heater and this to make the PERFECT cabin setup
Wow this project can be done in just around 30 bucks I can't belive it!
I'm going to give it a try, thanks DIY Perks!:D
That's pretty cool. I wonder if you could use the sunlight as the heat source (put a black plate on one side to heat up in sunlight), and then have it cooled from the bottom...
hey remember me? i commented on one of you videos when you had alot less subs saying you looked like a Game of thrones character! Its good too see how much your channel has grown!
I'm not sure if anyone else mentioned this, but why not fill it with water and put it in the freezer for a solid block of ice. I know you said snow and ice just seems a solid block in the tray would be easy prep also.
if connected to a boiler this can be genuinely useful, however a strict redesign is required
Great video. I own a thermoelectric pot, now I think I'll build one.
Great video, as always I must say!
Are these the same as "Peltier" elements? I've used these decades ago to cool down an experimental setup during my studies, but in this scenario the use looks like the absolute reverse 🙂
Have been meaning to combine something like this with a chilly-bin and a tealight clay pot heater. But with a temperature based polarity swap switch for keeping the chilly-bin cold and the heater hot. Then switch again to charge a battery. Have all the parts except for a chilly-bin.
Love your voice, your ideas, your video quality, I LUH U MAN.
That's a cool use of Peltier coolers. :)
Fantastic video! The links to the parts are not working for me on iPhone unfortunately.
I'm pretty sure that I'm some years late to be in with a chance of winning the four Native Union cables haha
And thanks for the video, it was a pleasure watching it :)
very cool project! The datasheet of the TEC1-12706 says Max. Operating Temperature: 138°C - wont it get hotter with 10 candles?!
